Application flied May 3, 191,6. Serial No. 95,215.

To all whom t may concern:

Be it known that I, ADoLrHUs Dirson- MEAU, a citizen of the United States, residing at Manistique, in the county of Schoch craft and State of Michigan, have invented new and useful improvements in Vrenches, of which the following is a specification.

My present invention pertains to sliding jaw wrenches of the handle-lever-grip type, and is designed more particularly as an improvement on the wrench constituting the subject of my Letters-Patent Number 1,175,934, dated March 21, 1916.

The object of my present invention is to provide a wrench similar in principle to the wrench of my patent supra, and embodying a simple, practical and highly eilicient and durable construction.

With the foregoing in mind the invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specilication, in which:

Figure 1 is a side elevation of my improved wrench. Fig. 2 is a transverse section of the same, taken in the plane indicated by the line 2-2 of Fig. 1.

Similar numerals of reference designate corresponding parts in both views oit the drawings.

The improved wrench comprises a fixed jaw 1, integral with which is a straight shank 2, reduced at its rear end, as indicated by 8, to form a handle.

F'ulcrumed at t on the shank 2 is the forward bifurcated portion `5 oi a handle 6 complementary to the handle 3. The handle 6 is arranged opposite one edge of the shank and handle 2 and 3, and the bifurcated portion 5 extends beyond the opposite edge of the shank 2 and is preferably rounded as indicated by 7 It will also be noted that at the tiret-mentioned edge the shank 2 is provided with an inclined abutment 8 against which a corresponding portion 9 of handle 6 is adapted to bring up, and that the sides of the bifurcated portion 5 are provided in their rear edges with wirereceiving notches 10, designed to coperate with the adjacent edge of the shank 2 in cutting wire or the like.

Riveted or otherwise fixed to or formed integrall with the shank 2 is an arm 11 that extends laterally from the shank and is provided with a guide aperture parallel to the shank, and rotatable rectilinearly in said aperture is the rear smooth portion 12 of a screw 13 which is also provided with a roughened finger portion 1li and a circumferential flange 15; said finger portion 14: and flange 15 being arranged in front and rear oitl the portion 7 of handle 6. rIhe arm 11 straddles the shank 2 as illustrated, and

its sides 16 terminate in inclined ends 17 which constitute stops for the correspondingly inclined edges 18 of the handle portion 5.

Slidable on the shank 2 is a jaw 19, opposed t0 the jaw 1, and formed in the said jaw is a longitudinally-disposed threaded bore which receives the screw 13. llhus by turning the screw 13 about its axis the operator is enabled to initially adjust the jaw 19 to suit the size of the work in hand.

In the practical use of the wrench, the jaw 11 is rst adjusted by manipulation of the screw 13 to approximately accommodate the wrench to the article to be turned. Then when the jaws 1 and 11 are properly positioned relative to the article, and the handles are gripped to place the opposed portions thereof in Contact, the jaws will be strongly held against the article and each of the handles will brace and lend increased strength to the other. On the other hand when the handles are relieved of pressure, the jaws 1 and 11 may be expeditiously and easily removed from the article.

Having described my invention, what I claim and desire to secure by Letters- Patent, is:

A. wrench comprising a fixed jaw, a straight shank fixed with respect to said jaw and having a reduced handle portion and also having an inclined abutment at an intermediate point of its length, a jaw slid able on said shank and having a threaded bore in its rear side, an arm iixed with respect to and extending laterally from the shank and having a longitudinally-disposed guide aperture and also having portions arranged at the sides of the shank and terminating in inclined ends, a screw arranged alongside the shank and in said bore of the sliding jaw and having a finger portion and a circumferential flange spaced there from and also havinga plain portion movable in said aperture, and a lever having a bifurcated portion straddling and pivoted to the shank and terminating in ends dis- In testimony whereof I have hereunto set posed between the finger portion and they my hand in presence. of two. snbsenibing flange of the screw and also having an in- Witnesses..
